- This invention relates to jewelrychains' of the ilexible type, and has for its mainfobject to provide a chain of this character, which will be more attractive in appearance than such mesh type jewelry chains made or proposedheretofore.

Another object of my inventiony is to provide a jewelry chain as characterized"hereinbefora Awhich is composed of pivoted linkelements, ex-

posed portions of the vlink members providing al new mesh design, th'e adjacent edges of such link portions being closely drawn'to one another, and

the chain still being flexible.

Still a further object of my invention is to provide a flexible mesh jewelry chain which will be adapted for comparatively easy and inexpen sive mass manufacture. Y Y

Further objects of this invention will be ap'- parent as the specication of the same proceeds. In the drawing forming a part of this specica-` tion and accompanying the same:

Fig. 1 is a plan view of a portion of mesh type jewelry chain, made according to one form of my invention;

Fig. 2 shows a blank used in manufacturing this form; and' Fig. 3 is an end view of a portion of the ready chain indicating a link element prepared and in position to be added thereto; this figure is on a larger scale than Figs. 1 and 2.

Referring now to the drawing', more in detail, by characters of reference, the numeral ID indicates my novel mesh jewelry chain, in general, the same being composed of blanks, generally indicated at II. These blanks will be cut out of an appropriate thin sheet of material as usual for such chains, like gold, and will have a central elongated web or main body portion I2, at the two sides of which will be formed diamond shaped arms I3 being alternately placed at the two sides of the central body portion I2. The adjacent corners I4 of the `diamond shaped arms may meet, indeed, there the material of the original sheet may be left intact during the operation of cutting the blank I I from such sheet.

'Ihe outer corners of the diamond shaped arms are continued in a comparatively long portion I5, which will be used as a locking or hook device for the chain.

When manufacturing thechain, a blank I I will be bent into the shape shown in end View in Fig. 3, and generally indicated by the numeral IIa.` When the blank is bent in said shape, as will be explained more in detail presently, it will be added to the earlier prepared portion IUa of the chain I0, in the manner indicated in Fig. 3.

Y lIt `will be seen that Vthe arm I3a of .the-bent blank'IIa', forming the link to be next added to the chain, willhe bent4 at an obtuse anglewith reference'to'the body portion fI 2a, the'angle' being smallrthanrusual with-other mesh type chains formed of links in a somewhat similar manner. The arms I 3d will be almost rectangularly setas `against the'body portion I2a. l f

The-outer'ends' I5a ofthe arma'being the lock- 'ing o'r hook portions thereof, as will be understood fand shown presently,will be `:bent very strongly lrearwardly almost in parallelism with the main portion I3a o-f the'arm.y f

A'comparatively small space,1indica'ted at I6, will be left between the inwardly turned locking portions I5a at the two sides of the'link member, ands-aid link member will be applied on the previously prepared portion Illa of the' chain, by `being pushed over thereof through said space I6, as indicated in Fig. 3,"bythearrow I'Ba. y

After pushing the new link over the existing portion 0f the chain to a desired predetermined extent, the arms at the two sides of the link will be pressed inwardly, as indicated by the arrows I1 and I8, by an appropriate tool or die, as it is well known in this art. Upon such inward pressing, the arms will take up a generally full right angular position against the body portion I2a, forming the upper and lower planes or surfaces I9 an'd 20, respectively, of the ready chain. Upon such nat pressing of the arm I3a, the outer ends 2l of the rearwardly turned locking extensions I5a will press against the body member I 2b of the link IIb, being the last'link in the chain previously finished, and will pull the body portion I2a, of the link I Ia to be added towards the ready chain, as indicated by the arrow 22, and upon the final pressing down of the arms I3a into the outer planes of the chain, the links will be closed upon one another to such an extent, that 4the edges 23 in the triangular pant ol the diamond I3, will meet, as indicated in Fig. 1, so that a beautiful pattern of diamond shaped elements will be shown on the surface of the chain, with very small, or practically no spaces between, the diamond shaped elements, and ne division lines between them, but the chain will still be flexible to aplimited extent suilicient to form an adjustable bracelet, or the like, from said chain.

It also Will be seen that upon such a pulling of the new link I Ia over the last earlier link I Ib and pressing its arms I 3 into the respective planes I9 and 20 of the chain, the front, substantially half triangular, portion 2470i the arms I3 of the new link I Ia will t into the substantially triangular and identical spaces 25 in the earlier n-y ished link Hb, and, vice versa, the rear half triangular portion 26 of the earlier link Hb will fit into the spaces 21 ofthe new link l la.

I may remark that other shapes than the diamond shape shown in the drawing may be given to the arms I3, and a chain constructed according to my invention, with such geometric contour for the arms and the spaces therebetween, and

upon such drawing close of the links ofthe adjacent arms, the respective portion of therarms in one link will exactly fit into the -corresponding spaces in the arms in the other links, and patterns of other designs than a diamond shape may be formed in the ready chain in such manner.

What I( claim as new and want to -protectby Letters Patent of the United States, is:V
